SOLID STATE LIGHTING - WHITE LIGHT

Solid state lighting has huge potential. It is estimated that as many as 12 Billion light bulbs are in use worldwide with perhaps 2 billion sold each year in the USA alone. The US is estimated at one-third of the total manufactured each year worldwide, or 6 billion bulbs a year. Quantum dot SSL has the ability to save over 90 percent of energy consumed compared to an incandescent bulb. While adoption would take time, the lower cost made possible by mass produced quantum dots could increase the rate.

Quantum Materials QDX™ Quantum Dots are better suited to work in solid state lighting than other quantum dots. Their high-heat resistanceg increases lifetime by their photostability, meaning they don’t experience the “droop” of other quantum dots. Their wider Stokes shift and narrow FWHM contribute to color purity thereby having the potential for better white light emission in conjunction with other color QD. Quantum Materials has a marked advantage as a supplier of QDX™ quantum dots to the lighting industry.

There are a number of different potential uses and applications. Quantum dots can be applied to a film and activated by a blue LED (photoluminescence). Quantum dots can be part of the LED device itself and be electrically stimulated to produce light (electroluminescence).
